or less, long slots 15 are formed in the bot-- tom of the casing 6, and the junction, at and between the lower ends of the partitions 12- and 13, rests on the parts of said bottom that are at and between the ends of the slots 15, and may be soldered or otherw se secured to such parts. The slots 15 extend lengthwise in the bottom of the casing, and are wide enough to open into both chambers 8 and 9 at their lower ends. In the lower part of the partition 13 is a row of holes 16 extending len thwise of said partition, and located just ehind the vertical plane in which are located the rear edges of the slots 15. The chamber 8 opens at each end near the top through one or more holes 17 properly located in the corresponding end wall 11; and the chamber 9 opens at each end near the top through one or more holes 18 properly located in such wall. Thereis a clear space between the partition 13 and the top of the chamber 8, as clearly shown at .19 in Fig. 3.

The suction-cu 5 is provided in the center on the back side with a knob or head 20, and this head is forced through an opening provided to receive it in the front side of the casing 6. In this manner and by this means the suction-cup is securely fastened to the casing. The suction-cup extends a sufficient distance be 0nd the vertical plane, in which is located t e front edge of the deflector 14, to prevent such edge from coming into contact with the glass 1, when the attachment is in placeback of said glass.

The heatin element 7 is located in and extends lengtl iwise of the compartment 10, and has attached to each end thereof a short, screw-threaded rod 21. The rods 21 pass throu h insulators 22--22 secured in oppositelyisposed openings provided to receive them in the end walls 11, and the binding-posts 3 are screwed onto said rods outside of said insulators. Thus it is seen that thecoil 7 holds the binding-posts 3 in place and the latter hold said coil in place, all through the medium of the rods 21. The conductors 2 are or may be attached to the binding-posts 3 in the customary manner. In practice, the suction-cup 5 is placed against the back side of the glass 1 in such a Way as to form a partial vacuum in said suction-cup and thereby insure the retention of the same in fixed contact with said glass. The casing 6 is thus supported from the glass 1 in position to project heat" onto said glass, but out of direct contact there with, and, consequently, not in position to cause the glass to become overheated. The proper attachment is made to conduct the electric current to and through the coil 7,

and said coil becomes heated to the required degree. A Air enters the bottom of the casing 6 through the slots 15, passes upwardly into the chambers 8, and 9, through the holes 16 into the compartment 10, and passes out of said chambers through the holes 17 and 18. and out of said compartment through the slot 19. The air which enters the compartment 10 is heated directly by the coil 7 in said compartment, and as it leaves said compartment is projected onto the glass 1 by the deflector 14. The air in the cham-- bers 8 and!) is heated indirectly from the coil 7 and the hot airin the compartment 10, and, upon escaping through the openings 17 and 18, rises and comes into contact with the glass. This air may have a tendency to fan out to some extent. The air from the compartment 10 passes upwardly, in contact with the glass, between said glass and the deflector 14. The air thus brought into contact with the glass is sufiicient in volume and sufliciently warm or hot quickly to melt any congealed moisture that may be on the outside of said glass, and to prevent the formation of frost and ice thereon.

When the attachment is no longer needed, the conductors 2 are disconnected, usually at their battery-circuit ends, although they might be disconnected from the bindingposts 3, and the casing 6 is removed after proper manipulation of the suction-cup 5 to release the same from the glass 1.

More or less change in the shape, size,.

construction, and arrangement of some or all of the parts of this attachment in addition to those hereinbefore-specifically pointed out, may be made without departing from the spirit of my invention, or exceeding the scope of what is claimed.

WINDSHIELD ATTACHMENT.

Application filed March 18, 1926. Serial No. 95,791.

My invention relates to improvements in devices adapted to beattached to glass, and more es ecially to the glass of automobile rind-shields, for the purpose o'fkeeping the ame clear in cold and stormy weather, and consists essentially of a peculiarly constructed, perforated casing having therein front and rear chambers and an intermediate compartment, a heating element in said compartment, with electrical connections therefor, and means to attach said casing to the glass of the wind-shield, together with such other parts and members as may be necessary or desirable in order to render the device complete and serviceable in every respect, all as hereinafter set forth.

The primary object of my invention is to produce a comparatively small or compact and light in weight, economical, simple, and highly efficient attachment, of the class described, which can be readily attached to and removed from the wind-shield of an automobile, and connected with and disconnected from the battery carried by said automobile, wherewith sleet, frost, and ice are quickly removed from the portion of said wind-shield which is adjacent to said attachment, or are prevented from formin or accumulating thereon, and this without anger of breaking or cracking the glass that supports the attachment.

Other objects and advantages will appear in the course of the following description.

I attain the objects and secure the advantages of my invention by the means illustrated in the accompanying drawings, in which- Figure 1 is a rear elevation of an attachment that embodies a practical form of my invention, showing the same in place behind the upper glass late of a wind-shield to which it is attac ed, adjacent to the lefthand edge of such plate; Fig. 2, an end elevation of said attachment and said plate; Fig. 3, a central, transverse, vertical section through said attachment, and also a cross section through said plate; Fi 4, a lon itudinal, vertical section throng the attac ment, taken on lines 4-4, looking in the direction of the associated arrow, in Fig. 3, and, Fig. 5, a bottom plan of the attachment casing.

Similar reference characters designate similar parts throughout the several views.

The hrst view is on asmaller scale than are the other views.

This device is intended to be attached to the inside of the upper lass plate of the wind-shield of an automo ile, at a point in front of the driver, but below his range of vision, and in the first three views a portion of such a plate is shown at 1.

In Fig. 1 electrical conductors are represented at 2 leading from two binding-posts 3 forming parts of the attachment. The conductors 2 are designed to be connected in any usual and well-known manner with the battery of the machine. The binding-posts are omitted from the last view.

A suction-cup 5, of ordinary construction, is preferably employed as the means for fastening the casing to the glass, and this suction-cup is also omitted from the last view.

The attachment comprises a casing 6 equipped with the binding-posts 3 and the suction-cup 5, and provided with a heating element, which latter may consist merely of a wire coil, as 7.

Within the casing 6 are front and rear chambers 8 and 9, respectively, and an intermediate compartment 10. The casing 6 has end walls 1111 which close the ends of the chambers 8 and 9 and the compartment 10.

'Although as herein illustrated the walls of the chambers 8 and 9 and the compartment 10 consist of a single strip of sheet-metal bent to form the sides thereof, with the end pieces 11 added to form the ends thereof, such casing may be differently constructed, and consist of more or less than these three originally separate pieces.

The front side of the casing 6 and of the chamber 8 is straight, and at the top the material, of which such casing is made, extends rearwardly and then downwardly, parallel with said side, to form a partition 12 between said chamber and the com artment 10. From the bottom of the ront side of the casing 6, the material is carried rearwardly, passing under the partition 12, and then upwardly in a curve which,

side of the casing 6 and the partition 13 atment, and means to conduct electricity to said heating element, of means to fasten said casing to a vertical support as a wind-' shield.

4. The combination, in an attachment of the class described, with a casing having therein complete front and rear chambers with perforated bottoms and ends, and an intermediate compartment which opens at the top between said chambers, and adjacent to the lower end into one of said chambers, a heating element in said compartment, and means to conduct electricity to said heating element, of means to fasten said casing to a vertical support, as a windshield.

5. The combination, in an attachment of the class described, with a casing having therein complete front and rear chambers and an intermediate compartment which opens at the top between said chambers, said chambers opening at the bottom through the bottom of said casing and said compartment opening adjacent to the lower end into one of said chambers, and that portion of the casing which contains the rear chamber extending over the top of said front chamber and beyond the vertical plane in which the front side thereof is located, to form a deflector, a heating element in said compartment, and means to conduct electricity to said heating element, of means to fasten said casing to a vertical su port, as a wind-shield, at a point sufficient y re mote from. such su port 'to prevent said deflector from 'touchlng the same.

6. The combination, inan'attachment of the class described, with a casing having therein complete front and rear chambers and an intermediate compartment which opens at the top between said chambers, said chambers opening at the bottom through the bottom of said casing, and adjacent to the top through the ends of said casing, and said compartment 0 ening adjacent to the lower end into one 0 said chambers, of insulators in the ends of said casing, rods in said insulators, a heating element in said compartment attached tosaid rods, and binding-posts attached to said rods outside of said ends.

7. The combination, in an attachment of the class described, with a casing having therein complete front and rear chambers and an intermediate compartment which open through the'bottom of said casing and through said casing at and adjacent to the top thereof, said casing extending over said front chamber and be 0nd the vertical plane in which is locate the front side thereof, to form a deflector, and a heating element in said compartment, of fastening means attached to the front side of said casing and extendin beyond the vertical lane in which the ront edge of said deector is located.

8. In an attachment, of the class described, a casing comprising end pieces, and a perforated strip of thin material between said end pieces to which the same are attached, and bent to form a straight front side and a curved backside and two partitions, whereby the casing is divided into front and rear chambers that open through certain of the perforations in said strip and an intermediate compartment which opens adjacent to the bottom through certain other perforations in said strip, and at the top between said chambers.
